Out of the many worlds these Gates can access, this one in particular leads to a sub-zero environment, desperate to cling to any life that can withstand its frozen temperatures
The Gate of Many Worlds is a unique pet new from v184.108.40.206. It is invincible and it attacks within a 3.5m radius - similar to close-up AoE devotions like Bull. While many other pet-builds use this off-hand to great effect, I’ve come up with something unique with it: I use specific pet items to convert 66% of Physical and 100% of Elemental Damage into Cold. As it stands, this pet has a total flat damage of 313 Cold Damage; that is slightly less than the 326 average damage from a 26/16 Briarthorn. For an item-granted pet, this is amazing, and the fact that it attacks in a AoE circle to prevent enemies from blocking it makes it even better.
*220.127.116.11 update: Thanks to the change in Conduits, the Conduit is no longer viable for Lightning / Cold Raven builds. On the plus side, the Will of Bysmiel amulet nows gives +1 to Occultist skills, so the only thing that’s lost is the Chaos resistance. Devotions were slightly changed to get the build up to 20K health.
The Winter King Helmet provides 50% Physical to Cold and 100% Lightning to Cold. The faction item Dreeg Mark of Chills gives you 100% Fire to Cold, and the other faction item Bysmiel’s Webweaver gives you 50% Physical to Elemental, equally distributed among Cold, Fire, and Lightning. Storm Spirit provides a huge amount of flat Elemental Damage, fully converted to Cold, so I take as many slots that give points to Storm Spirit while keeping the conversion. The rest of the items, including the faction rings, were for taking the Raven to 26/16.
The great thing about this build is that the weapon, the rings, and the medal are all faction items, and the Gate to Many Worlds item drops through Eldritch Totems. That means that once you get the helmet recipe, you are basically ready to rock. SR 80-81 is doable; Anasteria is difficult because her resist shred tears through the Briarthorn, but other than that, 20K is more than enough to handle any threat coming your way.
